Could the TEM investigation have led to recrystallisation?
Have you tried polarised-light microscopy to check the character of the
amorphous phase?
Cheers, Uwe

Dear François,
Maybe you have a strongly disordered system. Depending on the type of disorder
and the distribution of diffuse intensity, it can also have an influence on the
reflection profile (thermal diffuse scattering).

Betreff: Hyper-Lorentzian effect on quantitative analysis
Dear Rietveld users,
I have some industrial compound presenting a strong hyper-Lorentzian peak shape
(eta=1.1 with HighScore). When we calculate the amorphous content after an
internal standard addition, the result is 40%. The micro-absorption effect has
been minimized (mu of the internal standard is closed to the compound).
But with some electronic transmission analysis no amorphous is observed.
The question is : Does a strong hyper-Lorentzian peak shape could influence
quantitative analysis ?
François
